NATHANIEL E. CHASE, OF BOSTON, MASSACHUSETTS.

GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 247,167, dated September 20, 1881,

Application filed June 11, 1881.

To all whom "it may concern Be it known that I, NATHANIEL E. CHASE, of Boston, in the county of Suffolk and State of Massachusetts,-have invented a new and useful improvement in Portable Gas-Heaters,

of which the following is a specification.

My invention relates to an improvement in that class of heating devices used in connection with a gas-burner for heating liquids or solid substances; and the invention consists in an adjustable support or holder provided with legs having grooved lower ends, which are made to fit upon the projecting upper edges of a cylindrical casing made open at the bottom and provided with a wire-netting at the upper end, the said casing being supported by means of a frame upon the tube of a gasburner.

Referring to the drawings,Figure l is aperspective view of a device embodying my'invention. Fig. 2 is an elevation of a portion of the same. Fig.3 is a top view of the support in g-frame folded.

A is a cylindrical casing, made preferably of tin or sheet metal. It is entirely open at the lower end. The upper end is provided with a fine wire-netting, D.

To the lower edges of the casing A is attached a fiat metal piece, a a, as shown, to which is fixed a tapering tube, B, which is designed to fit over an ordinary gas-burner.

On the upper part of the cylindrical casing A is fitted a holder or support composed ot' two thin metal bars, 0 O, secured together at the center by a rivet, f, and provided each with legs 0 c, the lower ends of which are curved or grooved, so as to engage with a projection on (No model.)

the upper end of the cylindrical casing A, as shown at d d, by means of which the support or holder G C may be readily attached to or detached from the said casing.

The two bars 0 C may be folded together, as shown in Fig. 3, for convenience of packing and transportation.

When in use the tube B is fitted upon a gasburner. The gas is then turned on, and passing up into the casing becomes mingled with the large volume of air in said casing, and, being ignited above the wire-netting D, produces a very intense heat. On account of the fine-- ness of the wire-netting the gas and air do not pass at once through the netting, but on meeting the under side of. the netting a portion-0t the air and gas becomes deflected, and they are caused to reverberate within the casing and so become thoroughly mixed before passing through the wire-netting.

What I claim as my invention is- 1. The adjustable support or holder 0 O, in combination with the legs or supports 0 0, provided with the grooved ends 01 d fitting on the projecting edges of the casing A, as set forth.

2. The combination of the cylindrical casing A, open at the bottom and provided with the wire-netting D, the adjustable holder 0 (J o c, the frame or support an, and tube B, all as and for the purpose specified.

In testimony whereofI have signed myname to this specification in the presence of two subscribing witnesses.
